I know it's not qt, but qt has this notion of QWheelEvent::DefaultDeltasPerStep – maybe gtk has that too?
Anyway, I recently implemented a fix for a problem in the linux KDE application gwenview, where, when you used CTRL+Touchpad_scroll to zoom in/out, it was horribly sensitive (see here for bug/patch https://bugs.kde.org/show_bug.cgi?id=378584#c7). For the fix we would always accumulate deltas upon triggered events and only perform the action once the accumulated delta is greater than or equal to QWheelEvent::DefaultDeltasPerStep (at the same time resetting the accumulated delta to 0). Using the scroll wheel, the emitted delta is exactly QWheelEvent::DefaultDeltasPerStep, such that the action is performed at each turn of the wheel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
